[Bug 486906] [NEW] ubuntu 9.10 imagej "Plugins>Compile and Run..." does not work

[Brian King]

Public bug reported:

Binary package hint: imagej

I upgraded from Ubuntu 9.04 (fresh install) to Ubuntu 9.10 just last
night (great job, guys!). I opted to install the ImageJ package 1.43b-
1ubuntu1 (http://ca.archive.ubuntu.com karmic/universe Packages). I can
start ImageJ just fine from the Applications>Graphics menu (the
graphical icon in this menu does "imagej %f" according to its
Properties). It runs beautifully. BUT...

But when I select "Plugins>Compile and Run..." I get the error: "Unable
to find the javac compiler, which comes with the Windows and Linux
versions of ImageJ that include Java in the ImageJ/jre folder.<newline>
java.home: /usr/lib/jvm/java-6-openjdk/jre" In this case, I'm trying to
compile and run a Plugin (My_Integrator.java) in $HOME/.imagej/plugins.

So at this point, with apologies, it becomes confusing. I had been
trying to get ImageJ running (same bug!) on 9.04, so my system's java
use/preferences may have changed. So let me point out the following
behaviours, for different choices of jre (using "sudo update-
alternatives --config java" to toggle between different javas (javae??).

IF I CHOOSE "/usr/bin/gij-4.3" or "/usr/bin/gij-4.4", THEN I replicate
Bug #471127. In this case, implementing the "hack" suggested by linuxed
on that report/thread (editing "/usr/bin/imagej") has no effect and
ImageJ will not launch from the Applications menu. Command-line launch
gives the "Exception in thread "main" java.awt.AWTError: Cannot load AWT
toolkit: gnu.java.awt.peer.gtk.GtkToolkit..." message which - at first
glance - seems to be the same as in Bug #471127.

IF I CHOOSE "/usr/lib/jvm/java-6-openjdk/jre/bin/java" or
"/usr/lib/jvm/java-6-sun/jre/bin/java" THEN ImageJ launches/runs great!
However, when I attempt to "Plugins>Compile and Run..." I get the above
error. (Sorry! NEED to get this running, and am a bit of a java newb, so
though I understand repository-packagers aversion to non-free-as-in-
freedom java environments, I downloaded the Sun jdk yesterday... and
possibly Sun jre much earlier...)

I apologize if fixing Bug #471127 fixes this as well. But my guess is
that perhaps the Ubuntu repository packaging has environment variables
which aren't pointing in the correct place (I see that the package's
imagej.jar has a "hack" in it from previous instances of this problem -
found on the web...).

(Hopefully it will be possible to eventually just run ImageJ in all its
functionality directly from the Applications menu...)
